16 4g63 "mystery springs"

These were included in a 4g63T parts lot i bought and know nothing about them they came in a bag marked "new"

They have a green marking painted on them and unsure if they are stock or aftermarket. although seem slightly stiffer when compared to the stock springs

Will include a valve spring compressor for 4g63 engine aswell making this a great deal if you happen to know what the springs are!

The engine lot was all 92 6 bolt crank 4g63t
